Weight whack

ABSTRACT

A sheath ( 40 ) is formed with weighted portions ( 90 ) and attaching members ( 80 ) for attaching the sheath to the blade portion of a cricket bat. The weighted portions can be formed using receiving sections to accept weighted objects which are held in the receiving sections using weighted objects.

FIELD OF THE INVENTION

This invention relates to exercise equipment, and more specifically to an apparatus and method for strengthening and conditioning the muscles used to rapidly maneuver a cricket bat

BACKGROUND

In the sport of cricket a cricket bat is held by a batsman and used to strike a ball released by a bowler. Bowlers can release the ball at speeds in excess of ninety miles per hour and the batsman must be able to maneuver the bat in a rapid manner to strike a ball approaching at these high speeds. The cricket bat can weigh between two pounds and about three and a half pounds and maneuvering it in a rapid manner requires the use of certain muscles in the arms, shoulders and back. To successfully play the game of cricket it is therefore necessary to strengthen and condition the muscles necessary to rapidly maneuver the cricket bat. The currently available apparatus for strengthening and conditioning do not specifically target those muscles necessary for rapidly maneuvering the cricket bat. There is therefore a great need for apparatus that specifically targets the muscles used to rapidly maneuver the cricket bat. The instant invention addresses this need.

SUMMARY

The present invention provides a sheath for attaching to the blade portion of a cricket bat. The sheath is formed using a number of weighted portions along a surface of the sheath. If necessary multiple weighted portions can be formed on various and differing surfaces of the sheath. Any number of weighted portions can be formed on the sheath in varying weights and positions along the sheath. The weighted portions can comprise a receiving portion in which a weighted object is placed. The weighted objects can be between approximately 2 ounces and 16 ounces. In use, a cricket bat on which a weighted sheath is placed is swung to simulate the movement of the bat during actual use in a game. This movement will serve to condition and strengthen the muscles necessary for using the cricket bat.
